Abstract: In a bus bar assembly includes a magnetic body having at least a first insertion hole and a second insertion hole and a bus bar. The bus bar is configured so that directions of electrical current flowing through it are opposed to each other at least once. The magnetic body includes a middle leg in the middle region located between portions of the bus bar. At least the middle leg defines a gap rendering a magnetic field discontinuous. The bus bar is configured to extend through the first insertion hole of the magnetic body from a first side of the magnetic body to a second side opposed to the first side with respect to an extending direction of the bus bar and further through the second insertion hole from the second side to the first side. The middle leg is located between the first and second insertion holes.

Abstract: In a bus bar assembly including a magnetic body having insertion holes and a bus bar disposed through the insertion holes, the bus bar is configured so that directions of electrical current flowing therethrough are opposed to each other at least once. The magnetic body includes a middle leg in a middle region located between portions of the bus bar, where the directions of current are opposed to each other and end legs in end regions located opposite the middle region with respect to the portions. At least the middle leg defines a gap which renders a magnetic field produced by the current discontinuous.

Abstract: A method of purifying combustion gases by removing acid gases therefrom, wherein a stream of combustion gases is caused to flow in contact with a surface of an acid gas remover formed from a mixture including a calcium compound for neutralizing said acid gases, and a binder for holding together particles of the calcium compound. Also disclosed is an incinerator incorporating the acid gas remover.
